Abstract
The present disclosure concerns colouring agents for keratinous fibres, in particular for human hair, which—with respect to its weight—contain at least one compound selected from the group formed by oxidative dye precursors, direct dyes and mixtures thereof, from about 0.1 to about 5% by weight of dicarboxylic acid(s) containing from about 2 to about 10 carbon atoms and/or salt(s) of this(these) acid(s), from about 20 to about 95% by weight of water, and less than about 0.1% by weight of peroxy compound(s), to produce oxidative colouring agents with improved protection of fibres.
